Solution
Take log:
If y = log(x) then x = 10y
"Nice" answer, no approximations but help of a pocket calculator.
The solutions however are almost directly visible in the original equation.
This suggests that the equation can be solved without calculator.
There we go.
Keep in mind that
and the root may be rewritten as:
which converts the equation to
with the same answers.
